Authorities in the Chinese territory of Macau have ramped up security measures following the deadly Las Vegas shooting this month and unveiled plans for a series of mock attacks and crisis training to safeguard the world's largest gambling hub.

The new recommendations were laid out in a government statement following a meeting on Monday between Macau's gaming regulator, the Judiciary Police and representatives from the six licensed casino operators, which include Wynn Macau and Sands China.

The former Portuguese colony of Macau had seen heady gang violence and bombings until China took control in 1999. Since the handover, booming casino revenues have propelled the tiny enclave of 600,000 people to one of the world's richest cities.
